Project: Casino Games Mobile Application, 30+ Games With Admin Dashboard to manage overall applications

Throughout the project, I focused on the Admin Dashboard and developed over 100 Rest APIs. Additionally, I implemented socket events for real-time multiplayer game transactions. I was using Socket.IO for multiplayer player synchronization and chat functionality within the application. The tech stack I utilized encompassed React, Node.js, Express, Typescript, Prisma, PostgreSQL, Redis, and Socket.io. My primary responsibility centered around creating the Casino Heavy Competitive Algorithms, determining users' winnings in the games. I closely collaborated with the CTO to optimize the game algorithms and reduce API latency as much as possible. Initially, the project used a monolithic architecture, but later, I successfully converted it to a microservices architecture, effectively managing the Kubernetes aspect. I handled the deployment of the application to AWS DevOps and proficiently used Git throughout the project.

I worked into the Restaurant Management Application where I built the UI using React JS and backend in Node.js with Typescript. Concerning the UI, I worked on two parts: the Frontend Billing UI and the Admin dashboard application, both developed from scratch. Simultaneously, I created the Rest API to be consumed by the Frontend. Additionally, I integrated the Sendgrid API with Node.js for real-time order alerts, resulting in a 30% acceleration in order response time. I generated daily, monthly, and yearly sales and expense reports. Finally, I deployed the application using React and Node.js to the AWS Cloud Deployment, setting up the local MongoDB database

My primary responsibility involved migrating over 30 ASP.NET code segments to Node.js. Additionally, I focused on standardizing the generation of PDF files to ensure consistency across various operating systems—Windows, Ubuntu, and Mac—by implementing a solution in Node.js using Puppeteer.
